If the problem was caused
Can I install the new version?
Or be trashed phone?

Now my phone not working 3g in the 4.4 and 4.3

That's why I decided to change

1. The unique you can do is WIPE ALL and flash again the latest firmware android 4.4.2 through ODIN (maybe flash it 2 times for fix baseband)
2. 3G will be a problem of the config of ur phone, no of ur firmware. Call ur telephone company and they will help ya fixing the rest
3. Good luck
